Flamebar BW18 has been designed and developed to form a lightweight, highly durable fire rated ductwork system which complies with the latest European test standards, EN1366 Part 1, 8 and 9 and Classified under EN13501 with a fire performance up 180 min. The system is fabricated from galvanised steel, prepared and is then sprayed with a coating using a specially formulated water based compound. The coating contains selected mineral fillers and is applied to a nominal thickness of 2 mm. The ductwork is produced in sections and is assembled on site utilising FLAMEBAR gaskets and sealants. A thermal insulation, with a density of 105 kg/m³ is be applied around the duct. A single layer of 50mm to achieve up to EI120 and a double layer of 50mm to obtain up to EI180. The system has been successfully tested for international use, under cellulosic fire conditions, to give in excess of four hours fire resistance in the event of a fire. Flamebar BW18 fire rated ductwork is produced in sections and assembled on site utilising tested fireproof gaskets/sealants.
